Example 3:

the schemes of example 1 and example 2 are further described below in conjunction with specific working examples, which are described in detail below:

specifically, this anchor clamps suitable for irregular work piece forging and pressing usefulness when during operation/use:

step one, adjustment: adjusting the position of the object placing part by operating the driving limiting mechanism 4 and the connecting part according to the length of the engine part and the position needing forging and hammering; the square rod 412 is rotated, the square rod 412 drives the rotary table 410 on the square rod to rotate, the rotary table 410 drives the two adjacent first bevel gears 411 and the winding rollers 206 to rotate under the action of the two second bevel gears 418, the other winding rollers 206 rotate simultaneously through the transmission of the other second bevel gears 418 and the first bevel gears 411, the four winding rollers 206 rotate to release the four steel wire ropes 205 on the four winding rollers 206, the bottom plate 203 gradually descends along with the release of the steel wire ropes 205, and the square rod 412 stops rotating after the bottom plate descends to a specified position;

step two, fixing engine parts: placing the engine parts into the fixed box 1 and placing the engine parts on the placing part, operating and driving the limiting mechanism 4 to enable the non-Newtonian fluid to be filled into the fixed box 1 and matched with the placing part to limit the shaking of the engine parts; the engine parts are placed in the square frame 201 and placed on the bottom plate 203, the four square rods 412 are pulled upwards, the four square rods 412 push the four triangular rods 413 to move upwards, the triangular rods 413 drive the two push plates 414 on the triangular rods 413 to move, after the push plates 414 are contacted with the adjacent push plates 405, the push plates 414 push the push plates 405 to move along with the rising of the push plates 414, the push plates 405 push the connecting blocks 417 and the second bevel gears 418 to move, the second bevel gears 418 push non-Newtonian fluid in the water tank 401 into a space among the partition cloth 202, the bottom plate 203, the square frame 201 and the fixed tank 1 through the connecting pipes 404, the partition cloth 202 is matched to wrap the engine parts, so that the engine parts are blocked by non-Newtonian fluid and are not prone to shake when being forged and hammered laterally or longitudinally, when the push plates 414 move to the insertion rods 304, the push plates 414 push the insertion rods 304 to move first, the insertion rods 304 are finally inserted into the insertion grooves 415 under the action of the first springs 305, the push plate 414 is fixed; when the engine part needs to be taken down, the engine part is slowly pulled upwards, the engine part pushes the separation cloth 202, so that the non-Newtonian fluid flows back into the water tank 401 through the connecting pipe 404, and the engine part is separated from the square frame 201;

step three, changing into a dust collecting cover: operating the fixing mechanism 3 on the top of the fixing box 1 to separate the fixing mechanism 3 from the object placing part, moving the object placing part to the bottom of the fixing box 1, fixing the object placing part through the fixing mechanism 3 on the bottom of the fixing box 1, pulling outwards and rotationally driving the limiting mechanism 4, adjusting the direction of the driving limiting mechanism 4, limiting the object placing part to swing through the driving limiting mechanism 4, and limiting the object placing and dust collecting mechanism 2 to swing through the driving limiting mechanism 4; rotating the inserted bar 304 at the top of the fixed box 1, the inserted bar 304 drives the square 303 and the bolt 302 to rotate, so that the bolt 302 is separated from the inner part of the threaded hole 301, repeating the operation of the first step, so that the clip frame 201 moves to the bottom of the fixed box 1, rotating the four inserted bars 304 at the bottom of the fixed box 1, the four inserted bars 304 at the bottom drive the bolts 302 thereon to be respectively screwed into the inner parts of the four threaded holes 301, fixing the clip frame 201, pulling the supporting block 408 outwards, so that the rectangular rod 502 is separated from the inner part of the rectangular groove 501, turning the direction of the supporting block 408, so that the push plate 414 faces downwards, and after turning is finished, the supporting block 408 is loosened, so that the rectangular rod 502 is inserted into the rectangular groove 501 under the action of the third spring 503, at this time, the push plate 414 abuts against one side of the bottom plate 203, the push plate 414 and the square rod 412 cannot be separated from the rotating rod 409 under the action of gravity, and when wind gushes between the fixed box 1 and the partition cloth 202, the bottom plate 203 is not easy to swing along with the wind.
